Should you always favor xrange() over range()?
...ver, there are still a few cases why you might prefer range():
In python 3, range() does what xrange() used to do and xrange() does not exist. If you want to write code that will run on both Python 2 and Python 3, you can't use xrange().
range() can actually be faster in some cases - eg. if itera...

Minimizing NExpectation for a custom distribution in Mathematica
..., s, Log[x]]/x;
If we plot pdf2 it looks exactly as your Plot
Plot[pdf2[3.77, 1.34, -2.65, 0.40, x], {x, 0, .3}]
Now to the expected value. If I understand it correctly we have to integrate x * pdf[x] from -inf to +inf for a normal expected value.
x * pdf[x] looks like
Plot[pdf2[3.77, 1.34...

Why doesn't Python have a sign function?
... it.
>>> math.copysign(1, -4)
-1.0
>>> math.copysign(1, 3)
1.0
If you get sick of passing two whole arguments, you can implement sign this way, and it will still be compatible with the IEEE stuff mentioned by others:
>>> sign = functools.partial(math.copysign, 1) # eit...
